Minimelanolocus bicolorata sp. nov., Paradendryphiopsis elegans sp. nov. and Corynesporella bannaense sp. nov. from southern China

• Three new species of Minimelanolocus, Paradendryphiopsis and Corynesporella are proposed based on morphology.
• Keys to the species of Minimelanolocus, Paradendryphiopsis and Corynesporella are provided.
• New species, M. bicolorata, P. elegans and C. bannaense are compared with the related species.

Minimelanolocus bicolorata sp. nov., Paradendryphiopsis elegans sp. nov. and Corynesporella bannaense sp. nov., are described and illustrated. Minimelanolocus bicolorata is unique in possessing the schizolytic conidial secession and solitary, acropleurogenous, holoblastic conidia that are ellipsoidal, 3-euseptate, 30–35 × 7.5–9.5 μm, verruculose, pale brown, with an appendage at each end. Paradendryphiopsis elegans is characterized by monoblastic conidiogenous cells producing short chains of conidia that are 13–30.5 × 4–6.5 μm, 2–3-euseptate and fusiform to obclavate. Corynesporella bannaense is distinguished by terminal and integrated or discrete, monotretic conidiogenous cells that arise as lateral branches from the tip of the conidiophore and solitary conidia that are 12–16-distoseptate, smooth, obclavate, thick-walled, pale brown, and 100–140 × 10–14 μm. Keys to species of Minimelanolocus, Paradendryphiopsis and Corynesporella are provided.
